Syntax Error :
A syntax error is an error/mistake in the source code of a program. As computer programs must be thoroughly parsed for proper compilation, every aspect of the code that does not follow the syntax of the programming language results in a syntax error.
Different logical errors, which are errors in the operation or logic of a program, syntax errors are small grammatical errors, sometimes limited to a single character. For example, a missing semicolon(;) at the end of a line or an extra parenthesis at the end of a function can result in a syntax error. In the following PHP code, the second closed parenthesis would result in a syntax error because the function contains only one open parenthesis.
echo “Just test.”;
Some software development IDEs check the source code for real-time syntax errors, while others only generate syntax errors when a program is compiled. Even if a source code file contains a small syntax error, it prevents the successful compilation of an application. When you run a script through an interpreter, the script cannot be executed due to syntax errors. In most cases, the compiler or interpreter specifies the position (or line number) of the syntax error, so the programmer can easily find and correct the error.
These are spelling errors in your code that cause the program to stop working or run partially. Usually, you will also receive some error messages. They can usually be solved as long as you are familiar with the right tools and know what the error messages mean.

Symptoms of a Syntax Error
Each time a syntax error occurs, the final result can not access the particular program you want to access. The telltale sign would, of course, be the pop-up error message informing the user that such an error occurs.
Cause of a Syntax Error
This can be caused by several factors. Syntax errors are most commonly caused by spelling errors or incorrect punctuation. This is common when a program tries to translate from one platform to another. The problem can be exacerbated if the PC in question has a crowded record that has been damaged.
Fixing a Syntax Error
Syntax errors can often be corrected and corrected automatically. In some cases, however, manual editing may be required.
Steps to follow fixing Syntax Error:
- a) Open the computer code and compile the program.
- b) Locate the manual debug tool in the toolbar.
- c) On the Tool tab, look for Debug or Debug Compiler.
- d) Click on the result found.
- e) Check the code for errors.
- f) Correct any errors found.
- g) Save all changes and run the compiler.
- h) Restart your computer when the process is complete.
Syntax errors in C/C++
The errors that occur when you violate the rules for writing C/C++ syntax are known as syntax errors. This compiler error indicates something that needs to be repaired before the code can be compiled. All these errors are recognized by the compiler and, therefore, are called compilation errors.
Most frequent syntax errors are:
- Missing Parenthesis (‘}’)
- Value of a variable is printed without declaring it
- Missing semicolon(‘;’) like this:
- The syntax of a basic construct is written wrong. For example: while loop
In the given example, the syntax of a while loop is incorrect.
